SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 618,538, dated January 31, 1899.

Application iiled May 31, 1898. Serial No. 682,147. (No model.)

T0 a/ whom t may concern.-

Beit known that I, EDWARD D'. ETNYRE, a citizen of the United States, residing at Oregon, in the county of Ogle and State of Illinois, have invented certain new and useful Improvements in Sprinklers, of which the following is a specication.

The object of this invention is to construct a sprinkler-head, adapted for streetsprinkling in which a sheet of water is discharged and the amount discharged may be regulated.

In the accompanying drawings, Figure 1. is a plan view of the pipe connection with the sprinkler-heads. Fig. 2 is a vertical lengthwise section through one of the sprinklerheads, in which the cap is closed. Fig. 3 is a similar View in which the valve is open. Fig. 4 is a vertical section on dotted line a, Fig. l. Fig. 5 is an isometrical representation of the stationary section of the head. Fig. 6 is an isometrical representation of the adjustable cap. Fig. 7 is an isometrical representation of the packing located between the cap and stationary portion of the sprinkler-head. Fig. 8 is an end elevation of the sprinkler-head, in which the Valve has been removed. Fig. 9 is a vertical section on dotted line b, Fig. 1.

In the construction of sprinkler-heads, so far as known to me, the water has been discharged through a series of holes or perforations, each opening or perforation allowing a separate stream of water to escape, which when it falls upon the ground is in the form of drops and is soon enveloped in a covering of dust, which is soon blown away, and the dust adjoining the drop oi' water has not been moistened. I propose to overcome this objection by allowing a solid stream or sheet of Water to escape from the sprinkler-head, which when it strikes the ground will moisten all parts of it sufficiently to prevent the raising of the dust.

I have shown two of my improved sprinkler-heads connected to the water-supply pipe intended to be supported by the cart, a connection being formed between the Vertical pipe 1 and the tank or water-reservoir. A T 2 forms a connection between the branches 3 and 4 and the vertical pipe l. At the ends of the branches are located elbows 5. Into each is inserted a nipple 6.

The stationary portion of the sprinklerhead has a polygonal end 7, by which it is turned in connection with the nipple. The outer end of this stationary portion is flaring and in circular form. A recess 8 is formed at the outer end of the stationary portion, within which is placed a ring 9, of yielding packing material, nearly iiush with the edge of the stationary portion. A section 10 of the outer face of the stationary portion is cut away and beveled, and the remaining portion 11 has three lengthwise openings 12. A section 13, of elastic packing material, is placed over the section 11 of the stationary portion. A cap of cup form has a section 14 of its face corresponding to the packing 13, and holes 15 are formed through the cap corresponding with the holes 12 in the stationary portion. Bolts 16 are passed through the opening in the stationary portion of the sprinkler-heads, packing, and cap and by means of which the cap is clamped in connection with the stationary portion, the packing serving to separate the cap from the stationary portion, and an opening is left between the cap and stationary portion, with the exception of the space occupied by the sectional packing. A cupshaped valve 17 is of a size to pass over the cap and rests. against the packing-ring 9. Ears 18 extend from the end of the valve, having their ends perforated, and between them is pivoted a rod 19, held in place by a pin 20, and a block 21, of yielding material, is placed between the end of the rod and the valve. This rod 19 is bent to extend parallel with the lengthwise direction of the sprinklerhead and is guided in a guide 22, extending from the stationary portion. Two guides are formed on each head inorder that the head may be interchangeable for either side of the cart.

A lever 23 has a pivotal connection with the elbow 5 by a set-screw 24. This lever is curved to pass over the elbow, and to it is pivoted the end of the rod 19. A coiled spring 25 surrounds the rod 19 between the guide 22 and the lever 23. The free end of the lever 23 is supported by a bracket 26, secured to the branches of the water-pipes, a pin 27 limiting the outward movement of the lever, as shown at Fig. 9, and to the free end of the IOO lever is connected a rod 28, which is intended to connect with a foot-lever to be operated by the attendant.

In use the coiled spring 25 will hold the valve against the packing-ring 9 with sufficient force to prevent the escape of water. By pulling on the rod 2S the lever 23 will be moved until it strikes the pin 27, which will move the valve sufficiently to expose the opening between the cap and the stationary section of the sprinkler-head, and the coiled spring will. bring the valve into'its closed position when the lever is released.

The sectional packing 13 is very elastic, and by means of the bolts 16 the packing can be compressed to vary the size of the opening between the cap and the stationary portion of the sprinkler-head, and by meansof these bolts the cap can be adjusted to vary the size of the water-exit opening at any point, so that more or less water can be allowed to escape at any given section of the exit-opening.

It will be noticed that the water escapes from the sprinkler-head in a sheet,the thickness of which depends upon the distance between the cap and stationary portion of the head.

I claim as my invention- 1. A sprinkling-head composed of a main portion, a cap, a yielding packing located between them and holding them separated and leaving an opening for the escape of water,

means located opposite the opening for clamp; ing the parts together in a manner to admit of the adjustment of the cap to vary the size of the opening and a cup-shaped valve adapted to inclose the cap.

2. A sprinkler-head coinposed'of a main portion, a cap, a yielding packing located between them, and holding them separated and leaving an opening for the escape of water, means for clamping the parts together, a cupshaped valve and a packing-ring adapted to receive the valve.

3. A sprinklerhead composed of a main section, a cap, a yielding packing located between them holding them separated and leaving an opening for the escape of water, means4 for clamping the parts together, acup-shaped valve, and a packing-ring held by the main portion adapted to receive the valve.

4. A sprinkler composed of a main section, a cap, a yielding packing located between them holding them separated, and leaving an opening for the escape of water, means for clamping the parts together, a cup-shaped valve, a packing-ring held by the main portion adapted to receive the valve, a lever, a

connection between the valve and lever, and a spring adapted to hold the valve closed.
